White Oleander Tree 25G

White Oleander Tree – Nerium oleander (25 Gallon Pot) available in Jupiter, FL.

Bold, bright, and beautifully low-maintenance, the White Oleander Tree (Nerium oleander) is a classic choice for tropical and coastal gardens across South Florida. Grown in a 25-gallon pot, this semi-mature tree-form oleander delivers year-round evergreen foliage and bursts of clean white blooms throughout the warm season.

A member of the Apocynaceae family and the Magnoliopsida (dicot) class, oleander is prized for its toughness in hot, dry climates and its showy floral display. Its upright form and narrow, leathery leaves provide architectural structure, while its clusters of star-shaped flowers brighten up driveways, walkways, pool decks, and sunny borders.

This tree-form variety is perfect for gardeners seeking flowering height and privacy without the maintenance demands of fussier tropicals. With proper care, it thrives in coastal winds, sandy soils, and high heat—just what a Florida garden needs.

Sunlight Needs:

Performs best in full sun, where it will bloom most prolifically. A minimum of 6–8 hours of sunlight per day is ideal in South Florida conditions.

Watering Requirements:

Drought-tolerant once established. Water regularly during the first 6–12 months after planting to establish roots. After that, oleander can thrive with minimal supplemental watering, even during dry spells.

Soil Preferences:

Grows well in well-draining sandy or loamy soils. Tolerates slightly acidic to slightly alkaline pH levels. Avoid consistently wet soils to prevent root rot.

Fertilization:

Apply a balanced, slow-release fertilizer in early spring and again in mid-summer to promote blooms and foliage growth. Avoid over-fertilizing, which may reduce flowering.

Pest & Disease Tips:

Generally hardy, but monitor for aphids, scale, or oleander caterpillars, which can cause foliar damage. Use horticultural oils or biological controls if needed. Good air circulation helps reduce disease risk.

Maintenance & Pruning:

Prune in late winter or early spring to maintain shape and encourage fresh growth. Tree-form oleanders benefit from light shaping annually. Always wear gloves—sap can irritate the skin.

Why It Works in South Florida:

• Heat- and drought-tolerant

• Handles salty breezes and poor soil

• Provides year-round greenery and multi-season blooms

• Excellent for privacy screens, formal landscapes, and poolside elegance

• Attracts pollinators without attracting deer
